10 Claims. (Cl. 248-166)
This invention relates to a folding table or similar struc
ture and more particularly to improvements in corner ele
ments or the like for connecting a plurality of leg means
between the side members 21 and 22.
The members of the structure 20 are held together by
the plurality of corner components, there being four in
number, one at each corner of the structure 20.

of the side member 22 is similarly bored as at 42 (FIG
URE 4). When the corner element is in its supporting
position, a fastener, such as 1a pin 43, is passed through
the alined apertures. A similar pin at 44 is used as part
‘of the connection between the channel 37 of the other
corner element 26 and the associated end of the other
side frame member 21. The two pins 43: and 44 are

the pins 43 and 44 are removed, the pins 45 and 46 serve
as pivot means whereby the corner elements 25 and 26,
together with the cross member 23, may be swung as a
unit to a position such as that shown in FIGURE 2. In
the case of the other corner elements 27 and 28, the pivots
are shown at ‘48 and 49 and the removable pin for the
element 28 appears at 50, it being clear that there is a
similar removable pin between the corner element 27 and
the associated end of the other side member 21, as will
be clear from the empty apertures as shown in FIG
URE 2.

similar pins are provided for the four corners. Any suit
